Which hazard intensifies due to increased pyroclastic density?

A)Pyroclastic flow lateral blast radius
B)Tephra cloud condensation rate
C)Lahar vibrational wave propagation
D)Shield volcano surface-tension fracturing

💡 Explanation

Pyroclastic flows with greater density undergo increased gravity spreading, resulting in a larger ground hug which, therefore, amplifies the lateral blast radius; this happens rather than increasing condensation because the high T dominates.
